Smart Dimmer by Shelly + Excellent Home Assistant Integration

I don't use a lot of dimmers. A lot of people have asked me about smart dimmers. This is a review of the Shelly Dimmer. It works great. It is small and works with a physical push button, but most importantly it integrates wonderfully with Home Assistant. There is a custom integration in the HA Community Store called Shelly for Hass, and it works perfectly!

Thanks for the video! I didn’t know about the HACS Shelly addon, I love it! I recently bought 6 of these dimmers and I can’t wait to install them ;)

[@craig5365]

They have a great beta version of of the plugin that is awesome

[@NaydenSpirdonov]

As Bulgarian, I'm really proud Shelly is taking off and the work of this company did present solutions for home geeks and even professional use in a such a convenient way. As industrial electrician in the uk I'm doing a lot of automation of gates, motorised bolards and access systems so I loved the fact that a shelly device can add additional functionality and be easily integrated in to an existing systems where WiFi is present. I would be happy if shelly start doing devices with ethernet sockets or the ability of such a socked to be connected to a device because sometimes is much easier for me too pool cat5 or 6 compared to extending WiFi range and doing meshes and will be much cheaper for the client as wifi it's not convenient for just one device in the middle of the field.

[@Runehorn]

Wow that is awesome and simple! Have not picked Shelly or sonoff to get started with home automation, but this video pretty much was a slam dunk for shelly

[@RyanDuffy]

Awesome video. So grateful for your straight forward tutorial videos.

[@jon9947]

Another great video!

[@MatthewN8OHU]

Nice to see that this will work with a 3-way or 4-way switch setup, as I was hoping it would be able to do that. I have an idea about time-of-day dimming for a couple of places where I have those kinds of switches. I'd also be interested in seeing how they would work in a place like a bathroom at night, so folks don't get blinded in there.

[@PeterScargill]

Good advice about the dimmer - I just came back from Chicago where some of the guys still use incancescents - so the Shelly dimmer is likely to be useful. Here in the UK I now ONLY use LEDs and never use the dimmable versions, partly because they tend to be more expensive and partly as I use a lot of LED STRIP which of course can be dimmed by Tasmota. Nice to know the dimmer is out there.

[@DrZzs]

Hey Pete! Thanks

[@matthewnoecker5062]

excellent video as always ... just as a side note you do not need to use the app to get it onto your network. When you first power up the shelly device you can do a search for the WiFi AP of the device and connect to it. Then you can go to the devices built in web page and make changes to all the settings there (wifi, mqtt, calibration, time zones ....etc)

[@Meelobee]

100% agree, if you're in the market for smart dimmers, these are what you want.

[@richardheijdra5973]

Thanks for sharing helps me a lot.

[@neilbrookins8428]

I have 10 of these dimmers and will be getting more. You said they are designed for momentary push button switches. That is true if you want local dimmer control by holding the switch. But if you want to use a standard toggle switch that is also supported but you would need to use app or HA to dimm it. After much research and testing I found that Leviton 1256-W is the best switch to use with these dimmers. It allows push and hold up for brighter and push and hold down for dimmer. Or push either direction for toggle on/off. That way you don’t get frustrated when you push and hold and it goes the wrong direction of brightness. Also this switch allows for 3 way, 4 way and more controls. I.e. multiple switches for each dimmer circuit.

[@neilbrookins8428]

ttdrj I recommend using the “edge” choice for your situation. It will toggle the light state with a single flip no matter the current state and previous app usage. The other options won’t do that.

[@rychei5393]

I would like decorator switches on dimmable 3 way lights. How do I go about this?

[@neilbrookins8428]

@@rychei5393 if you can get decorator switches that have a spring return, then you can set the Shelly switch type to push button. Otherwise with a standard decorator switch just set Shelly to edge mode. But in the latter case no dimming available at the switch. As for the wiring method- just wire hot to the switch and the return from the switch goes to the switch input on the Shelly. You can put as many switches in parallel as desired for the push button type or use standard three way with traveler wires for three way. It’s the same as three way traditional but the “load” is the Shelly switch input instead of the light.

[@simonhersche6720]

Hi @@neilbrookins8428 , thanks for your comment here. What you describe is exactly what I'm trying to do. I want to install the dimmer behind my toggle switch. I only have one switch, so I wanted it to just turn on/off the lights. I hooked the switch to neutral and to sw1 and set button mode to edge. But sadly it did nothing. I checked the connections with the multimeter and eventough it's connected correctly it doesnt work. I also tried connecting the switch to live wire, but that didnt work either.

[@neilbrookins8428]

@@simonhersche6720 the correct connection is to wire the toggle switch between hot and sw on the Shelly. So that the sw pin is intermittently hot vs open.

[@4olovik]

great product! integration is awesome!

[@DrZzs]

Amen!

[@neilbrookins8428]

I hope you can do a Followup video with other features this dimmer has. My favorite is the calibration. This feature fixes the issue where some led lights dimm slowly at first and then quickly near the minimum brightness. i.e. are not linear control. After enabling the calibration feature, the controls are perfectly linear. So a light that is pulling 14watts at 100% bright will pull exactly 7 watts at 50% bright. And at 25% bright pulls 3.5 watts. I’ve never seen another device that has this feature. Also the temperature and power measurement features are nice to have too. Let’s also not leave out its limitations. Dimmer only supports 1.1 amps max. This is a lot less than the Shelly 1 which is 16 amps.

[@androidtakeaway5446]

Wow, I just got 4 x shelly 2.5 in the mail (Thanks @Shelly Cloud), but I think I'll still go for mqtt instead of the brand new integration. Nevertheless, thanks Dr. Zzs, great video. And thanks Hakana!

[@ashpatel1022]

Great video! I got this set up with my two Shelly 1’s with the Shelly button on some lamps. I don’t have it connected to the Shelly cloud. The Shelly app works without issue. But I’m having issues after setting up in HA with the Shelly HACS integration. The entity shows up, and works with some automations. After a little bit of time it becomes an orphaned entity and not usable through HA. It’s still accessible through the Shelly app. I’ve tried uninstalling and reinstalling the integrations and the HACS integration as well. Any suggestions?

[@mikosoft]

Anyone tested Dimmer SL (the one without neutral)? Do I need some kind of bypass load or whatever it's called on the lamp to prevent it from blinking like the Sonoff touch switch without neutral?

[@holygroundv3]

Hello, love your videos, see if you or anyone can answer this question, im moving to my first home and I've decided to make all the switches smart, watching your videos and my investigation I went with sonoff TX T2/T3 for same aesthetics throughout the house, but I want a dimmer in some areas so I got the shelly dimmer, I just thought how would it be possible to have both on the same line going sonoff(tasmotised) > shelly dimmer > light, how would the wiring setup be?

Hey, love the channel. Wondering if you could help me with something. I would like to know if I could use the shelly dimmer 2 to automate a dimmable LED lamp that I want to ramp up and down the intensity during the day. I only found videos on youtube on how to use the shelly dimmer only on switchs but I need it to be installed between the plug and the lamp. Could you please help me? Thank you very much

Dr. Z thanks for your videos. Im new to Shelly, i bought a dimmer 2 and i have already linked it with the app no problem. Im trying to use a momentary switch similar to yours but it does not dimmer im not sure why. HeLP Please!!! Thanks man

[@EsotericArctos]

@DrZzs Is this available outside of US yet or is it US only atm? Dimmers are great for giving that slight fade in and fade out. Also great for wakeup alarms and for "Movie" style scenes to dim lights as the movie plays. Also great if you use motions sensors for night lights. I'd be lost without my dimmable globes now. I saw another channel review the Shelly dimmer and it failed badly on Incandescent globes, but worked really well with dimmable LED's which is pretty weird. Most are the opposite. This was a while ago and guessing it was a beta version at the time. Is the Shelly integration based around the Cloud component or is it based on local control? Edit: Ignore that last question. You answered it for me lol :) That addon is freaking awesome. It has all the information you need to create any automation you want using all the Shelly information available.

[@UniKyrn]

I like dimmers in general, still have a lot of old bulbs around the house. The Wife though, with a motion detector, she wanders around the house at night or hits the bathroom, a rule to slowly brighten a bulb to 30% instead of a blast of light in the face? She Who Must Be Obeyed loves that. :)

Is their some hack where I could connect a second switch to a GPIO on both dimmers and somehow use HA to control the other dimmer, and vice-versa?

[@shentz2873]

Sorry if you have covered this before, but I am curious if you are ever concerned about adding too many wifi devices, instead of other wireless formats? Great content! Thanks!

[@EsotericArctos]

If you find you have so many WiFi devices that your network can't handle it, go and add a Ubuiqiti AP to your network and create a dedicated network for your automation stuff. I have over 70 WiFi devices, including sensors and switches on an ISP supplied Router and not having any issue. As long as you have enough IP Addresses and there is no client connection limitations, these are fine as they only transmit really small amounts of data.

Hi , after posting my question, I found your video on the shelly1 / sonoff mini comparision were you pointed out the issue with shelly not holding the wire tight, after playing around few hours I came up with a little technique to make the shelly better hold the wires, Just bend the top bare wire so it has an L shape, then push the wire inside in a way that 1 part of the l goes behind the latch upwards, then when you close the screw it will hold really firmly... I never done a video, but I might try to show this as it might help. Thank doc for your great vids,

[@whatevah666]

It does look good, the version you tested (0.1.5) does however NOT have support for temperature on the dimmer, something that's pretty usefull to use in an automation in case it gets toasty ;) The BETA version might have temperature added to it, haven't tried it yet.

[@DrZzs]

oh cool. I didn't know the dimmer had a temp sensor on it. I should have assumed since they seem to do that on a lot of their devices.

[@wolfmurphy]

Interesting device. Thanks. Does it truly respect no cloud? I've been lurking on smart home sites, getting ready to dip my foot in. I believe in local control as much as possible.

[@wolfmurphy]

I hadn't read of REST before. Found this artiv=cle that makes compelling argument for MQTT. Thoughts? www.bevywise.com/blog/mqtt-vs-rest-iot-implementation

it really is No Cloud, if you don't want it. That's a good discussion to have MQTT vs REST. I use both on different devices. I can't say there is a clear performance different. It seems like ReST is usually faster, but that's a subjective observation with an N of 1. I'd love to hear more experts weigh in on that debate.

Does using the physical switch update the app like the sonoff mini. So I don’t have to ask google to turn on for off or off for on because someone used the switch.

What are the odds! I just got my Shelly Dimmer today. I plan to put it on a closet light to dim it when my fiancé is still sleeping since we’re on different work schedules. I was hoping to be able to use my dumb on/off switch to control it, do you know if that works? Or does it only work with momentary switches? If it works, I’ll just use circadian_lighting to automatically set the brightness based on time of day.

[@samldev]

For anyone wondering, this dimmer can be configured as an edge switch in the settings, just like all other Shelly relays. So it works even with a dumb toggle switch!

[@DaveLassalle]

@@samldev And then you can set the brightness level on a schedule using HA or something else? I think that's what you were asking in your original question and I was hoping to do something similar, so the light could be controlled in the room with a regular switch, but if you turned it on in the middle of the night, it would only be, say 20% brightness, but during the day could be 80%.

[@samldev]
